Title: Improvements in and relating to automatic transmission for vehicles
Inventor: ATKINS ALAN JOHN
IPC: F16H61/02
Filed: 1960-07-07
Abstract: 960,420. Variable-speed gear; positive detents. AUTOMOTIVE PRODUCTS CO. Ltd. July 7, 1961 [July 7, 1960], No. 23787/60. Headings F2C, F2D and F2E. An automatic transmission for a vehicle comprises a driving sun gear 19 clutchable to an input shaft 1 by a centrifugally engaged dryplate type friction clutch 14 and meshing planet pinions 20 which mesh planet pinions 21 meshing a reaction sun 26 and an output ring gear 22 clutchable to an output shaft 5 by a dog clutch 29 for forward drive. An output ring gear 28 meshes the planet pinions 20 and is dog clutched to the output shaft 5 for reverse drive. During reverse drive the planet carrier 23 is stationed by a dog detent 31, 32. The planet carrier 23 is held by a one-way brake 24 for low gear, intermediate gear is obtained by holding the reaction sun 26 one-way by engaging a friction brake 27 which is connected to the sun 26 through a one-way clutch 25, and direct drive is obtained by engaging a wet plate type friction clutch 15. Clutch 15 and brake 27 are applied hydraulically, engagement being controlled by a valve coupled to an output driven governor and the engine throttle mechanism so that engagement is controlled in accordance with vehicle speed and engine load. Hydraulic pressure is supplied by a single output driven pump. The reaction sun 26 can be stationed by a brake 40 to give engine braking on hills. To allow for tow starting a manual selector mechanism can be held in a position bringing the direct drive clutch 15 into the hydraulic circuit so that as the vehicle speed increases the pressure built up by the pump increases and engages the direct drive clutch. Alternatively for tow starting the direct drive clutch may incorporate a one-way clutch as described in Specification 947,408. The gearing may be followed by an auxiliary reduction epicyclic gear comprising a driving ring gear 60, an output carrier and an axially slidable sun gear stationable by a dog detent 61 for reduced drive and meshing internal teeth formed on the planet carrier for direct drive. The manual selector lever can be moved beyond its reverse position to a park position in which an axially movable plunger 46 mounted in a bush 47 in a stationary casing is slid into one of a series of holes in a disc 45a splined to the output shaft. The plunger has longitudinal grooves containing balls 49 in rolling contact with the surrounding surfaces. In order to facilitate gear changing all the dog clutch teeth may be of the repelling type, alternatively or additionally drag torque may be introduced by lightly spring- engaging the centrifugal clutch. Specification 298,186 also is referred to.

Patent GB-532276-A (GB)
Title: Improvements in or relating to the control of hydraulic machinery
IPC: B66D1/08
Filed: 1939-08-24
Abstract: 532,276. Brakes. HYLAND, C. Aug. 24, 1939, No. 24329. [Class 78 (v)] In the control of hydraulic lifting machinery, such as cargo winches, a gravity applied brake is released by fluid pressure in the fluid supply pipe when the motor is started up. Fig. 1 shows a bell-crank 1 the short arm of which is connected by a link 3 to brake gear and the long arm is provided with a weight 4 and a foot plate 5. To the long arm is hinged at 6 the plunger 7 of a hydraulic ram 9 furnished with an inlet 10 and a leakage overflow duct 14. The pressure supply pipe 12 has its passage connecting it with the inlet 10 partially blocked by a loosely fitting adjustable screw 11. The blocked passage is byepassed by a conduit 15 fitted with a ball valve 16. When the motor is started to raise the load the operating pressure is admitted to pipe 12 and seeps past the screw 11 to raise the plunger 7 and release the brake. When pressure supply is applied to the opposite side of the motor the load starts dropping, and the weight 4 immediately falls to apply the brake, the valve 16 allowing fluid to pass from the ram to the pipe 12, which at first has zero pressure. The pressure fluid passes, however, through the brake-held motor and raises the pressure in pipe 12 to lift the ram and release the brake slowly. The brake and motor thus balance one another to allow the load to fall gradually. Foot pressure may be applied should the hydraulic system fail or an exceptionally heavy load be under manipulation.

IPC: H02H7/26
Filed: 1931-09-02
Abstract: 386,033. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. -(Assignees of Kennedy, L. F.; Apt. 401A, Lecomey Plaza, 58th Street, Philadelphia, U.S.A.) Sept. 2, 1931, No. 24687. Convention date, Sept. 2, 1930. [Class 38 (v).] In a system wherein a section is controlled by two or more circuit-breakers, each with its protective relay, means are provided for ensuring that the relay which functions first on fault conditions causes opening of all the breakers, the means comprising an additional relay for each protective relay and a single channel interconnecting said additional relays. In Fig. 1, the protective relays 16 (shown as directional relays) have contacts 24 connected across an opposed-voltage pilot circuit 20, 21 containing additional relays 19. Thus, whichever of the relays 16 closes its contacts first on fault energises both relays 19 to open the circuitbreakers 13, 14, In Fig. 2, parallel feeders 32, 33 interconnecting the stations 30, 31 are provided at each end with a circulating-current circuit 41 containing an overload winding 39 and the current-winding of a directional relay 40. If a fault occurs in feeder 33 near the station 31, the circuit 41 near that station will energize relays 39, 40, causing them to close contacts 50, 51 and make a circuit from the - pole of right-hand battery 46 through contacts 50, 51, current winding 45 of polarized directional relay 42 to the + pole of the battery section 46. The current winding 45 at the station-end 30 will also be energized in parallel over pilot wires 43, 44, so that both relays 42 close contacts 54 to cut out the feeder 33. Relays 40, 42 deflect in the opposite direction to cut out the feeder 32. If the pilot circuits break, both protective systems function independently but in their own time. The Specification also refers to earth-return pilot circuits and to carrier currents. Reference has been directed by the Comptroller to Specifications 346,518 and 355,013.

Abstract: 1,153,039. Treating gases with liquids. MO OCH DOMSJO A.B. 2 June, 1966 [2 June, 1965], No. 24689/66. Heading B1R. In the production of pure hot water from the hot waste gases from the burning of waste-liquid from sulphite or sulphate cellulose processes, the hot gases are introduced into a column 1 'at 7, saturated with liquid from spray nozzles 2 and scrubbed in a zone 3 with a neutral or alkaline aqueous solution to remove sulphur di-oxide, hydrogen chloride and other impurities, then passed upwardly through a droplet separator 5 into a multi-stage zone 6 wherein the purified gases are contacted with water, pure hot water is removed by a pipe leading to a tank 20. Each stage in zone 6 has water sprays 15 and a corrugated tray on which water in the stage is collected either for passage to a lower stage or withdrawal, the upper portions of the corrugations being provided with slots for the passage of gas. In an alternative arrangement the water collecting trays are imperforate but do not extend entirely across the column and are so dispersed that the gas follows a sinuous path. The water spray nozzles are in this case arranged in or above a gap between the end of a tray and the column wall. In a further modification multistage purification step and water washing steps are carried out in a horizontal vessel, the various stages of each step being separated by vertical partitions which causes the gas to follow a sinuous path. Preferably the liquid used in the purifying step has a pH between 7.0 and 10 and may contain "green" or "white" liquors, or sulphites or carbonates of alkali or alkalineearth metals, e.g. sodium sulphite or carbonate. Also in the scrubbing and washing steps rotary spray producing means may replace the spray nozzles described above.
